Javascript: How to allow `console.log()` in .eslint?

How to allow console.log() in .eslint?
I tried

"rules": {
    "comma-dangle": 0,
    "no-console": 2
  }

but don't work.

[ljharb]

no-console would need to be set to 0 to disable it. See http://eslint.org/docs/rules/no-console.html

eslint 0, 1, 2 means

http://eslint.org/docs/user-guide/getting-started#configuration

"off" or 0 - turn the rule off
"warn" or 1 - turn the rule on as a warning (doesn’t affect exit code)
"error" or 2 - turn the rule on as an error (exit code will be 1)

@xgqfrms-gildata I did

{
  "defaultSeverity": "error",
  "extends": [
    "tslint:recommended"
  ],
  "jsRules": {},
  "rules": {
    "no-console": 1,
    "max-line-length": [true, {"limit": 80, "ignore-pattern": "^import"}],
    "indent": [true, 2],
    "quotemark": [true, "single", "avoid-escape", "avoid-template"],
    "only-arrow-functions": [true, "allow-declarations", "allow-named-functions"],
    "prefer-const": true,
    "no-duplicate-switch-case": true,
    "interface-name": [true, "never-prefix"],
    "max-classes-per-file": false,
    "no-unused-variable": true,
    "object-literal-sort-keys": false
  },
  "rulesDirectory": []
}

and a npm clean and then run but I had Calls to 'console.warn' are not allowed anyways...

[loretoparisi]

...so it seems it works using

{
  "no-console": false
}

[ljharb]

@loretoparisi that might be coming from tslint, which is an entirely different tool than eslint.

For those looking for the exact solution:

"rules": {
    ...

    "no-console": 0,

    ...
}

For those looking for the exact solution:

"rules": {
    ...
    "no-console": 0,
    ...
}

It does not appear to be an _exact_ solution. I tried no-console with both the default off setting and 0. Neither hide the linter error on log statements

I'm still searching for a fix. It's not a blocker for my work. Just annoying because 1. it's a false positive, and 2. apparently simple solutions like this one don't work.

[ljharb]

@mjstelly it certainly works; often editors have to be restarted for any config change to be picked up, and you might have other configs applying to that file.

[mjstelly]

I don't doubt that it works for some. I did restart and retest. So, that's not the issue. But it's possible that something else may be overriding it. I don't have any idea at this point. I'll have to revisit the issue when I get time.

[mstosio]

I've got same problem, did you fix it somehow?

[mjstelly]

@mstosio No, I have not. Since it wasn't a blocker, I didn't have time to pursue it. It's just annoying AF.

[ljharb]

Make sure your editor is configured to use a local eslint only (if you have a global eslint, remove it).

[cyb3rsalih]

@ljharb What you mean about global and local eslint ? Could you explain ?

[ljharb]

@cyb3rsalih npm install -g eslint vs npm install eslint; you never want the former.

[whalemare]

adding extends airbnb solve this problem, but i dont now how

{
    "env": {
        "node": true,
        "browser": true,
        "es6": true
    },
    "parser": "babel-eslint",
    "extends": [
        "airbnb",
        "plugin:import/errors",
        "plugin:import/warnings"
    ]
}

[tbrophy]

_This is not just an issue with editor/IDE state._ Setting no_console to "off" or 0 does on work using a locally installed eslint module in the following environment, _from the command line_...

bash; 5.0.9(1)-release (x86_64-apple-darwin18.6.0)
node; v12.9.1
eslint; v6.3.0

env:
  browser: false
  commonjs: true
  es6: true
extends: 'eslint:recommended'
globals:
  Atomics: readonly
  SharedArrayBuffer: readonly
parserOptions:
  ecmaVersion: 2018
rules : BLAH, BLAH...

[ljharb]

@tbrophy in that example, you’re not using the airbnb config, so you may want to file an issue on eslint itself.

[tbrophy]

Oh yea, _riiiight_. That's what I get for coding with sunglasses on.

[Sagarsahu34560]

during the "hello world !" program in (JavaScript) BRACKETS I am unable to run it and it was showing error that...... (console) was used before it was defined..... please anybody help me out!!!!! It's really urgent.

[ljharb]

Not sure what program that is, but you do have to set the browser and/or node envs with the airbnb config for it to work properly.
